A trash bin equipped with an automatic lifting lid includes a lid mounted onto a bucket. The tensioning device includes a tension member that longitudinally transfixes the wardrobe rod formed as a tube. The nonlinear chirp includes an x2 or higher nonlinearity and is configured to compensates for the Self Phase Modulation characteristics of the fiber-based amplifiers such that fundamental light is generated that has a spectral E95 bandwidth within five times that of the seed light.
